Unformatted text preview: through the arms and legs, and then again through the sweaty skin of the feet, through the damp leather soles of the boots, and then to the floor (ground). Some of the current may flow through the heart and lungs. ü༏ What is the electric resistance for this current? Rwethand Rtotal = Rwethand + Rinternal + = 200Ω Rinternal (Rfootimmersed + Rdampsole) // (Rfootimmersed =200Ω + Rdampsole) Rfootimmersed = 200Ω + 200 Ω Rfootimmersed = 100Ω = 100Ω + (100 Ω +5000Ω)// (100 Ω +5000 Ω) Rdampsole Rdampsole = 200 Ω + 200 Ω + 2550 Ω = 2950 Ω = 5kΩ = 5kΩ ü༏ What is the magnitude of the current through the human body? I = 120V / Rtotal = 120V / 2950Ω = 40.7mA ü༏ What are the physiological effects of the electric shock on the human being? Respiratory paralysis can possibly occur. © 2013 Alexander Ganago Last printed 9/10/13 9:48 PM Page 13 of 15 File: 2013+F+314+HW+1+solutions.docx EECS 314 Fall 2013 HW #1...
